Long ago, in a land far away, I read an ancient tome. Its geologist author concluded that our species was a significant catalyst for erosion!

Quote:
"Human activity exceeds natural processes in many ways.

"For example, humans emit more CO2 than do volcanoes by quite a long way; humans move more material across the surface of the Earth than do rivers, landslides and floods."

~BBC~

Nice to read but in the BIG PICTURE means nothing. The planet itself is changing its face as I type,some by itself and some by human and animal activity. Now I can only surmise that the planet changing itself is not a self engineered plan. Which ever volcano blows first or hurricane forms first or is the biggest will change things the most. So all in all it means nothing
